Abstract
BACKGROUND Gastro-oesophageal reflux disease (GORD) is a long-term complication of achalasia treatments. The aim of our study was to evaluate the yield of prolonged wireless pH monitoring in patients with successfully treated achalasia and its influence on proton pump inhibitor (PPI) use. METHODS Twenty-five patients with achalasia who underwent prolonged wireless pH monitoring after a successful treatment with pneumatic dilation were enrolled. pH variables were analysed in the first 24 hours of monitoring to determine if tracings were indicative of GORD; the same variables were analysed in the following 24-hour period in order to obtain a worst-day diagnosis of GORD. PPI therapy before and after the test was recorded. RESULTS Five out of 25 patients had GORD diagnosis during the first day of monitoring and four of them had oesophagitis at endoscopy. During the following days of monitoring four more patients had a diagnosis of GORD. Out of the 25 patients, PPIs were started after the test in six asymptomatic GORD-positive ones, whereas prescription of PPIs was stopped without detrimental effect on symptoms in three GORD-negative patients. CONCLUSIONS Prolonged wireless pH monitoring is a useful test to be added to endoscopy in order to evaluate GORD and to optimise antisecretory treatment in successfully treated achalasia patients.

Abstract
BACKGROUND Achalasia is characterized by esophageal aperistalsis and impaired relaxation of the lower esophageal sphincter (LES). This contrasts with an insufficient LES, predisposing to gastro-esophageal reflux and Barrett's esophagus. The co-incidence of achalasia and BE is rare. Pneumatic dilatation (PD) may lead to gastro-esophageal reflux, Barrett's esophagus development, and esophageal adenocarcinoma. AIMS To determine the incidence of Barrett's esophagus and esophageal adenocarcinoma in achalasia patients treated with PD. METHODS We performed a single-center cohort follow-up study of 331 achalasia patients treated with PD. Mean follow-up was 8.9 years, consisting of regular esophageal manometry, timed barium esophagram, and endoscopy. RESULTS Twenty-eight (8.4%) patients were diagnosed with Barrett's esophagus, one at baseline endoscopy. This corresponds with an annual incidence of Barrett's esophagus of 1.00% (95% CI 0.62-1.37). Hiatal herniation was present in 74 patients and 21 developed Barrett's esophagus compared to seven of 257 patients without a hiatal hernia. Statistical analysis revealed a hazard ratio of 8.04 to develop Barrett's esophagus if a hiatal hernia was present. Post-treatment LES pressures were lower in patients with Barrett's esophagus than in those without (13.9 vs. 17.4 mmHg; p = 0.03). Two (0.6%) patients developed esophageal adenocarcinoma during follow-up. CONCLUSIONS Barrett's esophagus is incidentally diagnosed in untreated achalasia patients despite high LES pressures, but is more common after successful treatment, especially in the presence of hiatal herniation. Patients treated for achalasia should be considered for GERD treatment and surveillance of development of Barrett's esophagus, in particular, when they have low LES pressures and a hiatal herniation.

Abstract
BACKGROUND Long-term follow-up studies of achalasia after pneumatic dilation, mostly retrospective, have shown variable results. AIM To examine the outcome of achalasia after pneumatic dilation using a prospective follow-up programme. METHODS One or two dilations (first dilation treatment) in 77 patients to achieve stable (>1 year) remission and patients followed up with yearly clinical and manometric assessments. Endoscopy, pH monitoring and barium swallow were also performed. RESULTS A total of 69 patients achieved stable remission and were followed up for 5.6 years (3-10.7) [median (IQ range)], whereas six patients underwent cardiomyotomy and two experienced a perforation. Twelve of the 69 patients relapsed after 2.6 years (1.7-5.1): nine of 12 underwent one to two further dilations. Six-year remission rate (by Kaplan-Meyer estimates) was 82% after first dilation treatment and 96% after all dilations. Continuous antisecretory treatment was clinically needed in 16%, oesophagitis present in 7% and reflux pathological in 28% of the patients. Beneficial effects of dilation on oesophageal motility and on diameter of the oesophageal body at barium swallow were maintained during follow-up. CONCLUSIONS A management strategy including sessions of pneumatic dilation until stable remission and a standardized follow-up is highly successful in the long term. Gastro-oesophageal reflux is clinically relevant in a minority of patients.

Abstract
BACKGROUND Patients with achalasia require repeated invasive therapies and may experience multiple complications. The objectives of this study were to determine the incidence of such complications, causes of death, and life expectancy in 253 patients. METHODS Patients consisted of two groups: group A comprised 177 patients with newly diagnosed achalasia; group B consisted of 76 patients in whom the diagnosis had been established in external institutions. All patients regularly underwent structured interviews and were reinvestigated if changes in health status occurred. Survival rates were determined by Kaplan-Meier estimates and were compared with those of an average German population. Causes of death were determined from hospital records, information supplied by private physicians, and from death certificates. RESULTS Complete follow-up was obtained in 98.9% (group A) and in 100% (group B) of all patients. The observation period for group A ranged from 2 to 33 years and for group B from 2 to 26 years (disease duration: 4-68 years). The most frequent complications were reflux esophagitis (group A: 6.2%, group B: 19.7%) and megaesophagus (group A: 6.2%, group B: 21.0%). Thirty-six patients had died during follow-up. Five of these deaths were related to achalasia. In group A, the estimated 20-year survival rates in patients with achalasia [76% (95% confidence interval (CI): 66-85%)] did not significantly differ from those in controls 80% (95% CI: 71-89%). In group B, 25-year survival rates were also similar in patients [87% (95% CI: 78-97%)] and controls [86% (95% CI: 76-97%)]. CONCLUSION Patients with achalasia experience a significant number of complications. Causes of death and life expectancy, however, do not differ from those of the average population.

Abstract
Primary esophageal motility disorders are rare, the most common diagnoses being achalasia and diffuse esophageal spasm. Treatment aims to alleviate symptoms and may be medical, endoscopic, or surgical. Achalasia is most commonly treated by pneumatic dilatation or by laparoscopic Heller cardiomyotomy. Pneumatic dilatation is effective in 60-80% of cases, but functional results deteriorate over time. Surgical treatment is indicated when endoscopic dilatation is contraindicated or has failed. Functional results after cardiomyotomy are satisfactory in 90% of cases and results appear to be stable over time. The need for an associated antireflux procedure and the type of fundoplication remain controversial. For diffuse esophageal spasm, extended esophageal myotomy has yielded satisfactory functional results, but surgical treatment should be reserved for selected patients with severe symptoms.

Abstract
BACKGROUND It is generally considered that gastric acid suppression delays gastric emptying of solid meals because gastric hypoacidity impairs peptic digestion and antral triturition. Rabeprazole is one of the most potent acid suppressants. We conducted this cross-over study to investigate if rabeprazole delays gastric emptying of liquid nutrients, for which peptic digestion is unnecessary. METHODS On two randomized occasions, 13 healthy male volunteers underwent the (13)C-acetate breath test following ingestion of a 300 kcal-liquid meal. On one occasion, they had received 20 mg rabeprazole for the preceding 2 days and 1 h before the test. On another, they took no pretreatment. Based on 4 h breath samples, the half (13)CO(2) excretion time (t(1/2b)) and the time of maximal excretion (t(max)) were calculated as overall measures of gastric emptying. In addition, time profiles of gastric emptying were generated using the Wagner-Nelson analytical method, which creates the gastric emptying curve as accurately as the scintigraphy. RESULTS Rabeprazole significantly prolonged t(max) but unchanged t(1/2b). The gastric emptying profiles showed that rabeprazole evoked a segmental slowing of gastric emptying during 0.5-1.25 h of post-meal ingestion. CONCLUSIONS Rabeprazole suppresses gastric emptying of a liquid nutrient 0.5 h after meal ingestion. We have speculated that: (i) rabeprazole delays gastric emptying via a mechanism other than acid-pepsin maldigestion; and (ii) rabeprazole may intensify the post-gastric feedback regulation system (>0.5 h of post-meal).

Abstract
BACKGROUND Heller myotomy (HM) combined with an anti-reflux procedure has been shown to be effective for the treatment of achalasia, as postoperative gastro-esophageal reflux (GER) is observed in about 10% of the cases. Laparoscopy has brought an undeniable benefit in providing excellent visualisation of the gastro-esophageal junction (GEJ) without lateral and posterior dissection. Respecting the anatomical fixation of the GEJ seems to permit the performing of HM without an anti-reflux procedure, the need for which is therefore debatable. The purpose of this study was to analyse the results of this controversial procedure. METHODS A monocentric prospective study was carried out on 106 patients who underwent HM without an anti-reflux procedure. The postoperative assessment consisted of a manometry and a 24-hour pH study two months after surgery, and a yearly clinical examination for a minimum of five years. The data capture was done using a statistical analysis. RESULTS There was no mortality, one conversion to an open procedure, and four mucosal perforations. Postoperative morbidity was 2%. The average follow-up period was 55 months (range, 2 to 166), with 10 patients lost to follow-up. Good functional results were observed in 91.4% of patients at one year, and 78.6% at five years. Two months after surgery, a 9.4% prevalence of GER was detected in the pH study, and the lower esophageal sphincter pressure had significantly decreased. After a long term follow-up we observed an 11.3% global rate of GER. No repeat surgery was necessary to control postoperative GER. CONCLUSIONS Laparoscopic HM without anti-reflux procedure gives good functional results provided the anatomical fixation of the GOJ is respected.

Abstract
Malnutrition in the elderly is one of the greatest threats to health, well-being and autonomy, it is therefore crucial to understand and to contrast the causal factors of inadequate energy intake. This review focuses on the mechanisms of the so-called 'anorexia of aging'. In recent years, it has been shown that elderly subjects have abnormal peripheral signal patterns and alterations in central hypothalamic control relays. Negative feedback from impaired gastric motility, exaggerated long-term adiposity signals (leptin, insulin) and postprandial anorexigenic signals (CCK, PYY) seem to prevail over the central feeding drive. If nutritional strategies of intervention are to be improved, these data need to be taken into account.

Abstract
BACKGROUND Gastric emptying plays an important role in gastroesophageal reflux disease. Acid suppressants such as H2 receptor antagonists and/or proton pump inhibitors are often used in patients with gastroesophageal reflux disease. However, it remains controversial whether H2 receptor antagonists and proton pump inhibitors delay or accelerate gastric emptying. Here, the influence of acid suppressants on gastric emptying was evaluated via a cross-over study using the [13C]-labeled acetate breath test. METHODS Twenty normal male subjects without gastroesophageal reflux disease symptoms were enrolled. Gastric emptying was investigated five times in every subject by the [13C]-labeled acetate breath test with oral administration of the vehicle, domperidone, and three acid suppressants: ranitidine, famotidine and rabeprazole. Gastric emptying was estimated by the values of T(max-calc), T(1/2) and %dose/2 h calculated from the 13CO2 breath excretion curve. RESULTS Using the T(max-calc) values, rabeprazole, ranitidine and famotidine did not influence gastric emptying time in comparison with vehicle administration. Using the T(1/2) and %dose/2 h values, rabeprazole tended to delay gastric emptying. Domperidone produced a statistically significant acceleration of gastric emptying for all three variables (P < 0.05). CONCLUSION Oral dosage of the H2 receptor antagonists, ranitidine and famotidine, has no significant effect on gastric emptying. However, rabeprazole may delay gastric emptying more strongly than H2 receptor antagonists.

Abstract
BACKGROUND No data are available on the effect of hypnosis on gastric emptying. AIM To determine the effect of a hypnosis session on gastric emptying and dyspeptic symptoms. METHODS We studied emptying by ultrasonography and epigastric sensations in 11 healthy subjects and in 15 patients affected by functional dyspepsia under three conditions according to a fixed schedule: (a) basal, (b) after cisapride and (c) during a 90 min hypnotic trance. Eight healthy subjects repeated an emptying study listening to relaxing music. Statistical analysis was performed using the Friedman test or RM-ANOVA. RESULTS In dyspeptics, the postprandial increase in the antral area was significantly smaller during the hypnosis trance than under the basal and the cisapride conditions. For the patients gastric emptying was significantly shortened by cisapride, and even more by hypnosis (basal 274 +/- 16.8 min; cisapride 227 +/- 13.2; hypnosis 150 +/- 9.7) whereas for healthy subjects it was shortened only by hypnosis. The repeated study in healthy subjects listening to relaxing music showed no significant difference compared with the basal. Epigastric sensations were improved in dyspeptics by hypnosis, but not by cisapride. CONCLUSIONS Gut-oriented hypnosis is effective in shortening gastric emptying both in dyspeptic and in healthy subjects.

Abstract
BACKGROUND Twenty years ago an average of 1.5 Heller myotomies were performed per year in our hospital, mostly for patients whose dysphagia did not improve following balloon dilatation or whose esophagus had been perforated during a balloon dilatation. Ten years ago we started using minimally invasive surgery to treat this disease. STUDY DESIGN This study measures the impact of minimally invasive surgery with regard to the following: the number of patients referred for treatment; the number of patients who came to surgery without previous treatment; and the results of surgical treatment. Between 1991 and 2001, 149 patients had minimally invasive surgery for achalasia: 25 patients (17%) had thoracoscopic Heller myotomy and 124 (84%) had laparoscopic Heller myotomy and Dor fundoplication. Of the 149 patients, 79 patients (53%) had previous treatment (56 patients [71%], balloon dilatation; 7 patients [9%], botulinum toxin injection; 16 patients [20%], both) and 70 patients (43%) had none of these treatments. Mean postoperative followup was 59 +/- 36 months. Patients were divided into two groups: group A, operated on between 1991 and 1995; and group B, operated on between 1996 and 2001. RESULTS In the past decade, the number of patients referred for surgery has increased substantially--group A, 48; group B, 101; an increasing proportion of patients were referred for surgery without previous treatment--group A, 38%; group B, 51%; and the outcomes of the operation progressively improved--group A, 87%; group B, 95%. CONCLUSIONS These data show that the high success rate of laparoscopic Heller myotomy for achalasia has brought a shift in practice; surgery has become the preferred treatment of most gastroenterologists and other referring physicians. This has followed documentation that laparoscopic treatment outperforms balloon dilatation and botulinum toxin injection.

Abstract
Controversy persists in the surgical approach to treat esophageal achalasia. This investigation reports the long-term effects of esophageal myotomy and partial fundoplication in treating this disorder. From 1984 to 1998, 32 patients with achalasia underwent myotomy and partial fundoplication (Belsey Mark IV) using a left thoracotomy. The median follow up is 7.2 years. Assessments include clinical evaluation, esophagogram, radionuclide transit, manometry, 24-h pH, and endoscopy. There is no complication and no mortality. Preoperative assessment was compared with that in 0-3, 3-7, and 7-16 postoperative years. Clinically, the prevalence of dysphagia was decreased from 100% to 6%, 12%, and 13%, respectively (P < 0.001). Heartburn remains unchanged (P > 0.25). On radiology, the prevalence of barium stasis was decreased from 97% to 44%, 48%, and 47%, respectively (P=0.001), whereas a pseudo-diverticulum was observed in two-thirds of patients after operation (P=0.001). Percent radionuclide stasis at 2 min was measured as 70%, 17%, 20%, and 20%, respectively (P=0.001). Manometrically, lower esophageal sphincter (LES) gradient was decreased from 29 to 10, 9, and 9 mmHg, respectively (P=0.001). LES relaxation was improved from 41% preoperatively to 100% postoperatively at each postoperative period (P < 0.001). An abnormal acid exposure was observed in four patients after the operation. Endoscopy documented mucosal damage in three patients (P > 0.25). In conclusion, on long-term follow up, myotomy and partial fundoplication for achalasia relieve obstructive symptoms and improve esophageal emptying, and reduce LES gradient and improve LES relaxation. Acid reflux is recorded in 13% of patients and esophageal mucosal damage is identified in 11% of the patient population. A longer myotomy not covered by the fundoplication results in pseudodiverticulum formation and increased esophageal retention.

Abstract
Esophageal achalasia is a primary esophageal motility disorder of unknown etiology, characterized by absence of esophageal peristalsis and increased resting pressure of the lower esophageal sphincter (LES), which fails to relax appropriately in response to swallowing. Treatment is palliative and is directed toward elimination of the outflow resistance caused by the abnormal LES function.

Abstract
BACKGROUND Intrasphincteric injection of botulinum toxin has been reported as a safe and effective alternative treatment in oesophageal achalasia, especially in high-risk and elderly patients. AIM : To compare two formulations of botulinum toxin in the management of achalasia. PATIENTS AND METHODS We randomly compared the efficacy and safety of 100 U of Botox (Allergan, Irvine, USA) and 250 U of Dysport (Ipsen, Milan, Italy), injected through a sclerotherapy needle at the level of the lower oesophageal sphincter, in 78 consecutive patients with achalasia. Symptom score, oesophageal manometry and 24 h pH-metry were recorded (before and 1 month after therapy). Symptom score was also obtained 6 months after treatment. RESULTS One month after treatment, the effects of the toxin on symptoms and oesophageal tests were similar for both formulations. Lower oesophageal sphincter pressure decreased from 31 +/- 12 to 18 +/- 5 mmHg after Botox, and from 35 +/- 9 to 18 +/- 10 after Dysport. At the end of the follow-up period (6 months), symptom score decreased from 5 +/- 1.2 to 1.2 +/- 0.8 after Botox and from 5.2 +/- 1.5 to 1.5 +/- 1 after Dysport. Moreover, the percentages of patients who failed to respond to treatment (10% and 17.5%) and who relapsed during follow-up (12% and 24%) did not differ significantly. No patient complained of reflux symptoms after treatment, although abnormal acid exposure was documented in two subjects. CONCLUSIONS Both formulations of botulinum toxin have comparable efficacy in the treatment of oesophageal achalasia, for up to 6 months of follow-up.

Balloon dilation therapy under direct endoscopic vision was performed in three patients with esophageal achalasia. The Rigiflex through-the-scope balloon dilator, with a maximum diameter of 10-25 mm, was used for dilatation, with a 10-min inflation period. In all patients, dysphagia and regurgitation improved, body weight increased, and esophagography revealed a decrease in esophageal diameter. Our approach differs from standard methods used in Europe and America, in that the balloon has a smaller diameter and the duration of inflation is longer. Although our balloon dilator was small caliber, satisfactory results were obtained because of the longer duration of inflation. We conclude that balloon dilatation is the first choice for treatment of esophageal achalasia, and that to increase the safety of this technique, it is necessary to begin such treatment with a small caliber balloon under direct endoscopic vision.

Abstract
BACKGROUND We wanted to evaluate the clinical significance of the esophageal peristalsis that appears in some achalasia patients after treatment. METHODS We prospectively investigated the reappearance of esophageal peristalsis in 106 achalasic patients treated with forceful dilatation under endoscopic control (86 metallic dilatations and 20 pneumatic dilatations) and followed up clinically and manometrically for 1 year. Patients were divided in two groups in accordance with the presence (n = 26) or persistent absence (n = 80) of postdilatation esophageal peristalsis. RESULTS Before treatment, clinical data and manometric findings were comparable in both groups except for esophageal wave amplitude, which was higher in patients with postdilatation peristalsis (36 +/- 5 mmHg versus 24 +/- 2 mmHg, P < 0.05). One year after dilatation manometric findings were similar in the two groups, but esophageal wave amplitude remained higher in the group with postdilatation peristalsis (46 +/- 4 mmHg versus 21 +/- 2 mmHg, P < 0.05). The proportion of patients with persistent dysphagia was similar in the two groups (15% versus 12.5%). However, 10 patients with postdilatation peristalsis (38%) complained of chest pain as opposed to only 5 patients (6%) in the group with aperistalsis (P < 0.01). CONCLUSION The appearance of esophageal peristalsis after forceful dilatation in achalasic patients is frequently associated with persistent or new chest pain.

Abstract
Although achalasia is not a common illness in the United States and Europe, there continues to be a need for surgical therapy for treatment. Laparoscopic Heller myotomy and partial fundoplication has, for the most part, replaced open surgery (abdominal or thoracic) as the surgical treatment of choice. In order to perform this procedure well, one must select patients carefully, evaluate them fully, and adhere to the technical principles required to achieve consistently good results.
